Codimension two bifurcation in a delayed neural network with unidirectional coupling (Q1940742)

A delayed neural network with unidirectional coupling is studied. First, the authors prove the existence of a zero-Hopf bifurcation for such networks. Then, a normal form is used in order to predict zero-Hopf diagrams. Moreover, the existence of double Hopf bifurcation is proved for the coupled dynamical system. Numerical experiments illustrate the obtained theoretical results.
